Make Your Store
Readable by AI
Lumos generates and maintains your llms.txt, llms-full.txt and agents.md files, scores your store's visibility across ChatGPT, Gemini, Claude, and Perplexity and fixes what's holding you back — often in one click.
Built for the next generation of AI-powered search
The Shift to Generative Engine Optimization (GEO)
Search is evolving. Traditional SEO optimizes for Google's ranking algorithm — GEO optimizes for AI assistants that answer questions directly.
The Old World: SEO

The Cost of Invisibility:
Hallucinations
Without machine-readability, AI models guess your inventory or ignore it entirely.
Wrong Prices
AI might quote outdated or completely wrong pricing to potential customers.
Invisible Products
Your products don't appear in AI recommendations at all.
Lost to Competitors
AI recommends Amazon or competitors instead of your store.
Warning:
Unstructured Data detected.
AI Hallucination risk: High.

Frequently Asked Questions
What is an llms.txt file?
Think of it as a robots.txt but for AI. It helps Large Language Models understand the structure of your website so they can accurately retrieve information about your products.
How is my AI Visibility Score calculated?
We test real buyer questions about your niche against ChatGPT, Gemini, Claude, and Perplexity, then score your store out of 100 based on how often you're mentioned, where you rank, and the sentiment of the response.
What's the difference between Basic and Pro?
Basic ($9.99/mo) includes file generation, your AI Visibility Score, and access control. Pro ($24.99/mo) adds one-click auto-fixes, the agents.md Builder, Citations & Prompt Gaps, competitor tracking, and AI Analytics. Both plans start with a 7-day free trial.
Does it work with any Shopify theme?
Yes. Lumos works on the backend data layer of Shopify. It does not interfere with your visual theme, liquid files, or site speed.
Is my customer data safe?
Absolutely. Lumos never collects customer personal information. We only access product catalog information needed to generate your AI files, through Shopify's secure OAuth system.
Can I control what information is shared with AI?
Yes. You can hide prices, disable categories, block specific URLs or folders, and restrict specific bots or AI models from accessing your content.
